This invention relates to a Christmas tree decoration, and particularlyto a novel combination of reiector and lamp. It is now the commonpractice to decorate Christmas trees and similar objects with smallelectric lamps, which lamps are often of various colors. It is also nowcommon practice to use refiectors of various ornamental shapes `withsuch lamps. While such reflectors and lamps have been used, the lamps ofthe prior art have been of uniform color or have had all parts thereofof uniform degree of light permefability. Y'

It is an object of the invention to provide a lamp having thereonportions of diierent degrecs of light permeability and of variousormations.

It is another object of the invention to provide a Christmas treeelectric lamp having a bulb and plug, said bulb being colored andtranslucent for the greater pant of its area,

but having a portion adjacent the plug which is clear.

These and other objects andadvantages of the invention will be fully setforth in the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame parts throughout the different views, and in which,

Fig. 1 is a view in front elevation of a reector and lamp;

Fig. 5 is a view in front elevation of a relector and lamp of furthermodified form;

Fig. 6 is a horizontal section taken on the line 6 6 of Fig. 5, asindicated by the arrows. Y

Referrin to the drawings, in Fig. 1 is shown a re ector 10 made of sheetmaterial, preferably metal, the same having a shape, 1n front elevation,of a five-pointed star. o The reflector 10 is curved toward the front,

as seen lin the drawings, the curvature being uniform with the centralaxis extending normal to the reiiector at the center thereof. Thereflector l0 has its surface formed with a multiplicity of smallsubstantially semispherical depressions 10a. The surface of thereflector, including the depressions 10a, is quite highly polished so asto give a high degree of reflection. While these depressions may bedisposed in various ways and arrangements, in the embodiment of theinvention illustrated, they are shown as being arranged in rows parallelto the sides of the star form-v ing the reflector. The reiiector 10 hasa central aperture therein and a bushing or washer 11 of insulatingmaterial is provided havin a central aperture considerably smaller thanthe aperture in the reector, said Washer 11 being placed against therear side of the relector with its central axis co-axial with thecentral axis of the reflector. Said washer is secured to the reflectorby a plurality of circumferentially spaced and preferably pointed tangs10c extending through washer 11 and bent over on the outer side thereofin a manner similar to that shown in Fig. 4. A lamp 12 is providedhaving the bulb portion 12a of glass, or similar transparent material,vand the rear part comprising the threaded sleeve 12b and the tipContact 12a insulated from said sleeve. The lamp 12, preferably, isprovided with some coating or color, as indicated by the shading. Anyparticular color may be used. The lam 12 is provided with a portion12d,-and while this portion may be of various shapes and variouslyarranged, in the embodiment of the invention illustrated, it is shown asa zigzag band extending circumferentially about the bulb 12asubstantially at the widest portion thereof. The band 12d thus has aplurality of pointed portions 12e, and these are ar ranged with theircentral axes in alinement with or directly in front of the central linesof the respective points of the reliector 10. It may be stated that theortion or band 12d is of different color or e ee of li ht permeabilitythan the remain er of the ulb 12a and while various degrees of lightpermeabilitmay be used, as many different colors, in t e embodiment -ofthe invention illustrated, the band 12d is shown as belng clear.

In operation, the reflector and lamp disclosed will be mounted on aChristmas tree, or other Christmas decoration, in the usual manner, byscrewing the sleeve V12b of the lamp into the customary lamp socket, thereflector 10 being clamped or held between the lamp and lamp socket.When the lamp 12 is illuminated, the color in the main portion of thebulb will be reflected from the surface of the reflector 10 so that saidreflector will show the color from the bulb in the shaded -portion 10b.The band 12d, however, will cause the surface of reflector l() to show adifferent reflection about the border of the same, as indicated by theunshaded portion in Fig. 1, thus forming two zones of differentreflecting effect on the reflector. If the band 12d is clear, thisportion of the reflector will show with a very high light. If the band12d is of a different color, this color will be reflected about the edgeof the reflector 10. A very striking and beautiful effect is thusobtained on the surface of the reflector 10. The pointed portions 12e asstated are circumferentiall alined with the points or zones of the reector so that the border of said reflector is bright, as shown by theunshaded portion in Fig. 1.

In Figs. 3 and 4, a different form of reflector 15 is shown having aplurality of radially extending points 15e. The surface of reflector 15is also highly polished and provided with a multiplicity ofsubstantially semi-spherical depressions 15a, such as shown in thedrawing. Reflector 15 is also curved forwardly uniformly about a centralaxis` and is provided with a central aperture 15b. A washer or bushing16 of insulating material engages the rear of reflector 15 and is heldthereon by aplurality of circumferentially spaced tangs 15e passingtherethrough in the same manner as already described for washer 11 inreflector 10. A lamp 17 is provided having the bulb portion 17 a whichis Coated, or otherwise colored having the threaded sleeve 17d insulatedfrom the tip contact 170. The bulb 17a is provided with a portion 17?)of a dierent degree of light permeability from the remainder of the bulband while this portion may be of various shapes and arrangement, in theembodiment of the invention illustrated, it is shown as a circular band.The portion 17?) may be either of a different color or may be clear.

When the reflector 15 and lamp 17 are assembled on a Christmas tree orother similar device, as already described for lamp 12 and reflector 10,the color on the main portion of bulb 17 will be reflected from thecentral part of the reflector, as indicated by the shading 15d in Fig.3. The band 17 o, however, will emit light of a different coloring orintensity which will cause a different reflection from the outer ends ofthe points 15a, as indicated by the unshaded ortions in Fig. 3, thusgiving zones f di erent reflecting effect. If the band 17?) be clear,this latter portion will show quite bright and if the band 17?) be of adifferent color, this color will be reflected from the portion outwardof the portion 15d. A beautiful and striking effect is thus produced.

In Fig. 5, another form of reflector 20 is shown having its peripheryformed with a plurality of semi-circular lobes 20a. The surface of thereflector 20 is also highly polished and provided with a multiplicity ofsmall semi-spherical depressions 206 similar to the depressions 10a.While the depressions QO may be variously arranged, in the embodiment ofthe invention illustrated, they are shown as disposed in a double rowabout the outer edge of the reflector 20 and also extending inwardly inradial lines in double rows. Reflector 20 is also provided with a washer21 extending across the central aperture in reflector 20 secured theretoin a man ner already described for washers 11 and 16. A lamp 22 isprovided having the usual bulb portion 22a, the rear sleeve portion 22?)insulated from the tip contact 220. rlhe bulb 22a will be coated orotherwise colored and the same is shown as having circumferentiallyspaced portions 2205 of a different degree of light permeability thanthe remainder of the bulb. While the portions 22?) may be variouslyarranged, in the embodiment of the invention illustrated, they are shownas extending radially and outwardly toward the pointed end of the lampbulb. Portions 22a? may be either clear, or of a dierent color from theremainder of the bulb.

In operation, when the reflector 2O and lamp 22 are assembled and held,as above described, and the lamp illuminated, the color on the mainportion of the bulb will be reflected from the reflector 20, asindicated by the shaded portions in Fig. 5. The portions 22d, however,will cause portions or zones of a different reflective effect onreflector 20. The portions 22d will be disposed with their central linesin alinement with the radial line extending between the lobes 20a, ateach `side of which latter lines the rows of depressions 20?) aredisposed. The radial rows of depressions 20o will, therefore, beilluminated by the lightissuing from the portions 22d, and if theportions 22d be clear, these radial rows will be highly illuminated anda very bright reflecting effect secured. It' the portions 22d be of adifferent color from the remainder of the bulb, this color will bereflected along the radial rows, as indicated by the unshaded portionsof Fig. 5. A very handsome and striking effect is thus produced.

The reflector illustrated is substantially the same as that disclosedand claimed in applicants U. S. Patent No. 1,617,221 issued Feb. 8th,1927.

From the above description it is seen that applicant has provided anovel and ellcient electric lam for Christmas trees and one which willglve new, important and pleasing results. The ortions of the lamp whichemit different kin s or colors of light lwill produce diierent effectson the various reflectors 10 which may be used therewith which effectswill be very pleasing, beautiful and highly ornamental. It is alsopointed out that when the lights are used without reflectors as iscommon on Christmas trees, the lightwill shine through the clear portionand will illuminate other objects on the tree. With the structure shownin Fig. 6 the objects in the rear of the lamp and in the rear part ofthe tree will be illuminated, as trees are often placed in corners of aroom, the rear of the tree tends to be dark. With such lamps asdisclosed this part of the tree will be illuminated and beams of lightwill shine thereinto giving a very pleasing and ornamental effect. It

is also pointed out that by having a clear portion on the bulb moreradiation of heat isv obtained. As is well lmown, Christmas tree lampsget quite hot due to the translucent coating used to get the colorthereon.

It w1ll, of course, be understood that various changes may be made inthe form, details, arrangement and proportions of the parte without dearting from the sco e of the invention, w ich, generally state consistsin the novel parts and combinations of parts v disclosed and deiined inthe appended claims.
